Daily more people are getting rich through bitcoin and other cryptocurrencies. It can be through trading, gambling, mining or various other services and in specific holding. Users who invested at least $10000 - $15000 by January month of ongoing year probably could have turned rich if he's in a third world country.
A lot of people managed to enlarge their capital even if they invested in Bitcoin this year. Let us say they spend tens of thousands for BTC when it was about 4K, and later, they sold it for 8K, now they are waiting for the next investment.
Looking at the volumes, it is clear that a lot of the investors are currently accumulating Bitcoin (and the other cryptocurrencies such as Ethereum and Bitcoin Cash). They will be setting targets such as $15,000 per coin or $20,000 per coin. So the impact from those users who are booking profit at 8K levels will be more or less neutralized.
I think once should fix the target before investing and after investing he only have show patience and dont sell your investment until it gets higher more than double and gives you target price, I have invested my money at the price of 6k which is good to buy but I have plan to sell it for 20k so I will have to hold it with patience until then.
